Background technology
In cell dyeing process, for fear of different reagent, between sample, pollute mutually, conventionally can utilize transfer pipet to coordinate rifle head to realize reagent, the transfer of sample, concrete is, rifle head is the disposable product that adopts plastic material to make, multiple rifle heads are placed on the rifle headstock, transfer pipet moves down, its bottom and the opening part that penetrates rifle head, the opening and the transfer pipet that are the rifle head of taper closely cooperate and are fixed together, complete reality, after the transfer of sample, need to return the rifle head having used once, this just needs to rely on the Tuo Qiangtou mechanism being installed on cell-stain apparatus, existing de-rifle head mechanism structure is comparatively complicated, and needing to rely on the air pump being connected with transfer pipet inflates transfer pipet, utilize and compared with atmospheric pressure, rifle head is returned from transfer pipet, the reliability of this Tuo Qiangtou mechanism is poor, in the time that reality is used, because rifle head may exist mismachining tolerance in process of production, cause some rifle head to coordinate with transfer pipet comparatively tight, although some rifle head and transfer pipet can be fixed, but there is certain gap in cooperation place, therefore, utilize air pressure to move back the mode of rifle head, being difficult to all rifle heads of assurance can both return smoothly.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of Tuo Qiangtou mechanism of cell-stain apparatus, and it has higher reliability, can effectively overcome the defect that rifle head can not be returned.
For achieving the above object, the utility model adopts following technical scheme:
The Tuo Qiangtou mechanism of cell-stain apparatus, comprises,
Mount pad;
The transfer pipet that at least one is fixed on mount pad bottom and extends along short transverse;
Movable be arranged on the portable plate on mount pad, be provided with the through hole passing for transfer pipet on this portable plate, the periphery of through hole is formed with in the time that portable plate moves downward with respect to mount pad top downwards presses the top splenium of the end, the rifle crown on transfer pipet;
For the driven unit that drives portable plate to move with respect to mount pad along short transverse.
The width of through hole be greater than transfer pipet diameter, be less than the diameter of rifle cephalic par.
Portable plate posterior edges upwards bending forms a plate, and what slided respectively in the both sides of this web joint is installed on the line slideway that is positioned at mount pad both sides and extend along short transverse.
Driven unit comprises the motor of body partial fixing on mount pad, be synchronously connected in the rotating shaft of motor and the drive lead screw extending along short transverse, coupling be socketed in the feed screw nut on drive lead screw, web joint is fixedly connected with feed screw nut.
The beneficial effects of the utility model are:
Than existing Tuo Qiangtou mechanism, of the present utility model simple in structure, and can guarantee that rifle head departs from transfer pipet completely, be especially applicable to the structure that multiple transfer pipets are taken arms side by side, what make that rifle head on multiple transfer pipets can be synchronous takes off, and has higher reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is scheme of installation of the present utility model;
Fig. 3 is use view of the present utility model;
Wherein: 10, mount pad; 11, installing plate; 12, crossbeam is installed; 13, fixed head; 14, line slideway; 20, portable plate; 21, base plate; 22, through hole; 23, web joint; 30, transfer pipet; 41, motor; 42, drive lead screw; 43, feed screw nut; 50, rifle head.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
As shown in Figure 1, 2, 3, for the Tuo Qiangtou mechanism of a kind of cell-stain apparatus of the present utility model, it comprises mount pad 10, multiple transfer pipet 30, portable plate 20, driven unit, wherein, mount pad 10 comprises an installing plate 11, is fixed on the installation crossbeam 12 of installing plate 11 bottom front surface, and multiple transfer pipets 30 form a line and its upper end is installed on installation crossbeam 12, portable plate 20 comprises being positioned at installs the below of crossbeam 12 and the base plate 21 parallel with crossbeam 12 is installed, these base plate 21 rear sides upwards bending form a web joint 23, above-mentioned installing plate 11 both sides, rear surface are respectively arranged with a line slideway 14 extending along short transverse, what slided respectively in the both sides of web joint 23 is arranged on two line slideways 14, portable plate 20 can be moved up and down with respect to mount pad 10 along short transverse, on base plate 21, be provided with multiple through holes 22, the plurality of through hole 22 is corresponding one by one with transfer pipet 30, transfer pipet 30 is connected in the through hole corresponding with it 22, the width of this through hole 22 is slightly larger than the diameter of transfer pipet 30, when avoiding portable plate 20 to move with respect to mount pad 10, transfer pipet 30 collides with base plate 21, the width of through hole 22 is slightly less than the diameter of rifle head 50 top ends, that is to say, rifle head 50 can not be passed by through hole 22, the periphery of through hole 22 forms one for pushing up the top splenium of pressing rifle head 50 top ends, when rifle head 50 being housed and on transfer pipet 30 downwards in the time that portable plate 20 moves with respect to mount pad 10, the top splenium of through hole 22 peripheries can push up the top end face of pressing rifle head 50 downwards, rifle head 50 is moved downward with transfer pipet 30 to depart from.
